Furthermore, tbe' piti'oniof the layers 2, 3, which is at theperiphery of tbe tire is relatively nearer to the educ olf' tbe seidlayers und nence is inore easily stretci'nible.

The fourth layer, denoted by e, is new stretched, on outside oi theloyers 2, 3, in the saine inanner as the layer l, its edges entendn ingfrom mornin to margin 'of the tire.
